Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700170, here are decompositions:

139 + 8700031 = 8700170
151 + 8700019 = 8700170
163 + 8700007 = 8700170
211 + 8699959 = 8700170
223 + 8699947 = 8700170
277 + 8699893 = 8700170
313 + 8699857 = 8700170
439 + 8699731 = 8700170

Showing the first eight; more decompositions exist.
